Muhammad says: I asked Sayyiduna Jabir (may Allah be pleased with him) when did the Messenger of Allah (peace and blessings be upon him) perform Jumu'ah? He said: We would perform Jumu'ah with the Messenger of Allah (peace and blessings be upon him), then return and let the camels rest. Ja'far, the narrator, says: Letting the camels rest would be at the time of the sun's decline.
